If it came still governed at 63 it probably has a custom tune from the company that owned it that is defueling above 63.

May need a stock Cummins tune flashed into it.

Things that would help to know

What is boost doing at 63 is she screaming trying to make power? If it has a boost gauge should be hitting 30-32psi at full chooch.

Needs an EGR tune-up exh gas/IMAP/EGR diff sensors replaced.

Sure others will TuneIn with more information
